This invention relates to snubbers for motorvehicles and has for its object the. production of a simple but effective device of this character which may be quickly applied to the spring of the'vehicle without any con nection withthebo'dy otthe car. 1

Thisresnlt is obtainedby the mechanism illustrated in the accompanying drawing. *For the purpose of illustrating the invention, one preferred form thereof is; illustrated-in the drawings, this form "having been found to give satisfactory and reliable results, althoughit is to be understood that the various instrumentalities of which the invention consists canbe variously arranged and. organized, and the invention is not limited to the recise arrangement andorganization of t iese instrumentalities as herein showniand describedexcept as required by the scope of the appended claims.

' Of the drawings:

Figure 1 represents an elevation of one end of avehicle spring with an attachinentsecuredthereto embodying the principle ofthe present invention. i

FigureQ represents a horizontal section of same on line 2, 2,. on Fig. 1 looking upwardly,and V Figured represents a vertical section on line 3, 3,011 Fig. 1.

Similar characters indicate like parts "throughout the several figures of the drawin a it the drawings 10 is a portion of a vehicle sprin of usual construction composed ofa plura ity of leaves as shown, some of these leaves being longer than otherswith each end of the lower leaf 10* looped about a pin 11in a bifurcated support 12securedtiothe chassis of the vehicle in any well known manner.

y While onlyoneend of the spring 10 is shown inthe drawing, it must be understood that theother end is the exact duplicate of the ortion illustrated. l

' T e loop 13 of the inner lea-f 10* around the pin .11 forms shoulder 14 against which bears one end of aplate 15 the center portion of which. is free from contact with said lower leaf 10 of the spring 10, while the opposite ends thereof contact therewith.

traddling the spring 10 is a stirrup 16 theupper endsof which extend through a member 17 and have, threaded thereto adjusting nuts 18 and lock nuts 18*.

; I Extending through this stirrup l6 is a bar 19 having a curved portion 20 to, form aseat for the lower cross member 16* of the stirrup lfi. I y y he seating of this cross member 16* in the curvedportionx20 prevents end movement of the bar 19 and forms a fulcrum about which saidbar is adapted .to move.

This bar 19 is made of resilient metal and one end. thereof extends for some distance toward the center-of thevehicle spring 10 and contacts near its extremity with the under face of the leaf 10*, being curved slightly at this point as indicated'at 21 so thatthe contacting end may haveslight movement endwise ofsaid leaf 10"' y The opposite end of the bar 19 has an up- 1 -When making this adjustment the bar 19 will move about a fulcrum made by the upper end ofthe support 22 seated in the concave reeess23c I i The center of. the spring 10 may be secured to the body of. the vehicle in any well known manner. i

Under ordinary conditions the spri .10 y

will operate without affecting the snu her mechanism, but when the .vehiclemoves. over an unusually roughroad, the inner end of the bar 919 will be pressed downwardly about its fulcrum l6. and the support-22 will bemoved upwardly strengthening the outer end of the spring where said spring is the weakest.

Moreover this stiffening of the spring 10 prevents any excessive. movement thereof and itVOlllS all excessive jounclngof thevehicle body.

The seatingof the support 22 in the concaved recess 23 retains the end of plate 15 alwaysin contact with the shoulder 14. and prevents any end movement of said plate.

As the oppositeend of the plate 15 is positioned between the side members of the stirrup 16,said plate cannotmove sidewise.

The side members of the stirrup 16 and the seating of the support 22 in the transverse concaved recess 23 of plate 15 prevents any side movement of the bar 19.

his makes a very cheap construction of snubber which may be applied quickly to any form of vehicle spring without necessi tating the use of expensive labor.

Most snubbers now on the market, have one end secured to the spring and the other end secured to the body of the vehicle, and consequently an uneven snubbing action is imparted to the body of the vehicle.

In this device, the whole snubber is securedto the spring and any snubbing action is taken up in the spring itself before it can be imparted to the body of the vehicle.

The tension of the spring is made variable by the application of this snubber mechanism.

The snubber mechanism furthermore acts as a check on the spring on its rebound as the pressure of the plate on the leaf 10" tends to keep the spring straight, but as this pressure gradually diminishes, the spring 10 will return to its normal position with gradually increasing speed.

It is believed that the operation and many advantages of the invention will be understood readily without further description.

Having thus described my invention, I claim:

1. The combination with a leaf vehicle spring having a shoulder at the end thereof,

" a stirrup depending from said spring; a

resilient bar supported thereby having on one side of said stirrup a long arm bearing against the under face of said spring and an upwardly extending support on the other side of said stirrup; and a late on said support contacting at its ens only with the under face of said spring. I

2. The combination with axleaf vehicle spring having a shoulder at the end thereof,

i a stirrup depending from said spring; a

resilient bar supported thereby having on one side of said stirrup a long arm bearing against the under face of said spring and an upwardly extending support'on the other side of said stirrup; and a plate on said support contacting with the under face of said spring, the outer endof said plate bearing against the shoulder of said spring.

3. The combination with a leaf vehicle spring having a shoulder at the end thereof, a stirrup depending from said spring; a resilient bar supported thereby having on one side of said stirrup a long arm bearing against the under face of said spring and an upwardly extending support on the other side of said stirrup; and a plate on said support contacting at its ends only with the under face of said spring, the inner end of said plate extendin through said stirrup.

4. The combination with a leaf vehicle spring having a shoulder at theend thereof, a stirrup depending from said spring; a resilient bar supported thereby having on one side of said stirrup! long arm bearin against the under face of said spring an an upwardl extending supporton the other side of said stirrup; and a curved plate on said support contacting with the under face of said spring, and havin a. concaved seat to receive the u per end 0 said support. 7

' 5. The combination with, a leaf vehicle spring having a shoulderat the end thereof; a memberfextending transversely of said sprin a stirrup havi its side members exten 'ng through sai members; nuts threaded to thejends of said side members; a resilient bar fulcrumed on said stirru with a .long arm extending toward the mi dle of thespring and contacting at. its end with the under face thereof, said bar at its outer end having an upwardly extending support; and a yielding plate fulcrumed on said support free from contact with said spring except at its ends and of which the outer end bears against said shoulder.

6.
